CSBT-4805 - Double Canister Studs with Debris Catcher, Pumping Ring & Heavy Duty Bearing & Taper Ring Drive

The CSBT-4805 is a Double Cartridge Mechanical Seal, with heavy duty bearing, pumping ring and taper disc drive designed specifically for mixers, agitators, and reactors operating in critical process environments.

Engineered for reliability and efficiency, this innovative rotary seal with resilient stationary faces, features monolithic and hydraulically balanced seal faces, ensuring superior performance under varying pressures and speeds.

Designed for API Plan 52, 53 and 54 systems, the CSBT-4805 delivers enhanced safety, extended seal life, and reliable performance, making it the ideal choice for high-performance mixing and reaction equipment.

Key Features:

  • Double Seal – Provides optimal sealing for high-end, critical process applications and demanding process conditions.
  • Integral Heavy Duty Bearing - Supplied with double spherical roller bearing ideal for high shaft load support. Can be supplied without bearing or with low/medium shaft load carrying bearing.
  • Barrier Pumping Ring - Promotes barrier fluid flow through the seal, aiding the thermosyphon / convection effect and helping to keep the seal faces cool.
  • Hydraulically Balanced Seal Faces – Minimizes wear and enhances seal longevity, reducing maintenance and downtime.
  • API Plan 53/54 Compatibility – Ideal for pressurized barrier fluid systems, ensuring zero process leakage and enhanced safety. Can also be employed in unpressurised Plan 52 barrier systems
  • Debris Well - Catches any seal face wear/particles preventing entry into the process. Particles are removed from the seal via applying vacuum through the Debris Out (DO) orifice.
  • Stainless Steel Wetted Parts – Corrosion-resistant components for long-lasting durability in aggressive chemical and industrial applications.
  • Cartridge Construction – The cartridge design provides easy installation and replacement, reducing assembly time and maintenance complexity.
  • Resilient Mounted Stationary Faces – Provides a modicum of self-aligning to improve seal longevity.
  • Integral Double Lip Seal - Prevents dust and debris collecting around outboard seal faces in top entry applications. Supplied with Drain connection orifice for leak face leakage detection.
  • Taper Ring Shaft Clamping - Heavy Duty shaft shafting.
  • Monolithic Seal Faces - Monolithic (one piece) seal faces are the face of choice for high temperature applications over shrink fitted seal faces with differential thermal expansions of the bi-materials.

Upgrade your mixers, agitators, and reactors with the CSBT-4805 – where precision engineering meets modularity.

Safe Operating Limits:

This seal incorporates best practice features and innovation as detailed in our technical blogs and white papers.

** Apply "industry standard" Pressure, Speed and Temperature de-rating factors, by shaft size and application. The safe seal performance characteristics are typical characteristics for each variable in isolation. The individual upper limit values of each variable should NOT be used in multiple combinations of Speed, Pressure and Temperature. Contact our Technical Sales Department for further details.
